Michael Kerrisk f202015b45 execve.2: Linux now imposes a floor on the ARG_MAX limit
Starting with Linux 2.6.23, the ARG_MAX limit became settable via
(1/4 of) RLIMIT_STACK.  This broke ABI compatibility if RLIMIT_STACK
was set such that ARG_MAX was < 32 pages.  Document the fact that
since 2.6.25 Linux imposes a floor on ARG_MAX, so that the old limit
of 32 pages is guaranteed.

For some background on the changes to ARG_MAX in kernels 2.6.23 and
2.6.25, see:
    http://sourceware.org/bugzilla/show_bug.cgi?id=5786
    http://bugzilla.kernel.org/show_bug.cgi?id=10095
    http://thread.gmane.org/gmane.linux.kernel/646709/focus=648101,
    checked into 2.6.25 as commit a64e715fc74b1a7dcc5944f848acc38b2c4d4ee2.

Also some reordering/rewording of the discussion of ARG_MAX.

README

This package contains Linux man pages for sections
2, 3, 4, 5, and 7. Some more information is given in the
`Announce' file.

Install by copying to your favourite location.
"make install" will just copy them to /usr/share/man/man[1-8].
"make" will move the pages from this package that are older than
the already installed ones to a subdirectory `not_installed',
then remove old versions (compressed or not),
compress the pages, and copy them to /usr/share/man/man[1-8].


Note that you may have to remove preformatted pages.

Note that sometimes these pages are duplicates of pages
also distributed in other packages. This has been reported
about dlclose.3, dlerror.3, dlopen.3, dlsym.3 (found in ld.so),
about resolver.3, resolv.conf.5 (found in bind-utils),
and about passwd.5, and mailaddr.7. Be careful not to
overwrite more up-to-date versions.
Reports on further duplicates are welcome.
Formerly present and now removed duplicates:
 exports.5 (found in nfs-server-2.2*),
 fstab.5, nfs.5 (found in util-linux-2.12*),
 lilo.8, lilo.conf.5 (found in lilo-21.6*).

Copyrights: These man pages come under various copyrights.
All pages are freely distributable when the nroff source is included.
